Add option to scale watermark relative to cropped image size

[cmjns]

Is your feature request related to a problem? Please describe. When applying a watermark the mark is scaled relative to the original image size rather than to the cropped image size.

Describe the solution you'd like I'd like the option to scale the watermark to the cropped image size so all watermarks come out the same size

Alternatives A checkbox or a dropdown selection to chose "Scale to Original" or "Scale to Cropped", or just change the behavior as I'm not sure if the current behavior is a feature or a bug.

I'm using version 4. I saved my watermark settings as a preset. When applied to an uncropped image, The watermark was small. When applied to a cropped image, the watermark was much bigger.

Note that I'm using a PNG image, not the internal darktable watermark. Perhaps the behavior I describe is particular to a user defined image watermark?
